HYDRAULIC SYSTEM

1. STRUCTURE

The hydraulic system of the M5040, M6040 and M7040 tractor is composed of a 3-point hitch, remote hydraulic

control for implements, power steering, PTO clutch and shuttle clutch.

This system has the following functions.

1. Raise and lower implements connected to the 3-point hitch with external hydraulic cylinders. The hydraulic lift is

subject to position control and draft control (mixed) control.

2. Draw hydraulic power from auxiliary control valve to operate implement hydraulic cylinders.

- Implements with double acting cylinders can easily receive, hydraulic power drawn from the quick coupler.
- Auxiliary control permits simultaneous operation of implements powered by hydraulic pressure along with

operation of 3-point hitch.

- Oil flow from 3-point hitch pump can be connected with oil flow from auxiliary control valve.
- Operating pressure is 19.6 MPa (200 kgf/cm

2

, 2847 psi).

- Maximum of three remote valves or 2 valves with a flow control valve.
